SPECIFICATION forming part of Letters Patent No. 789,601, dated May 9, 1905,.

Application filed August 6, 1903. Serial No. 168,477.

T ttl/Z whom, 72b'- mfty/ con/cern,.-

Be it known that I, GEORGE WV. Fos'rEn, a citizen of the United States, residing at Testfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in finding-Machines, of which the following is a specification.

My invention relates to winding-machines, and more especially to that class of windingmachines in which the cop is rotated by contact with a driving drum or roll; and my invention consists in certain details of construction whereby to secure the better lay of the thread with a more uniform and stable winding and to facilitate and cheapen the manufacture and insure a greater rapidity of action, as fully set forth hereinafter and as illustrated in the accompanying drawings, in which- Figure 1 is an end elevation, in part section, of su iicientof a winding-machineto show my improvements; Fig. 2,21 longitudinal section of part of the machine. Fig. 3 is an enlarged side view of some of the parts seen when looking from the center of the machine toward the right, Fig. i. Fig. 11 is an enlarged side view of some of the parts seen when looking `from the right, Fig. 1. Fig. 5 is an inverted plan of one of the tension devices; Fig. 6, an enlargeiil side view illustrating part of the thread-guide-actuating mechanism indicated on a smaller scale in Fig. 2; Fig; 7, a section on the line 6 6, Fig. 6; Fig. 8, a side view showing my improved Vform vof cop-holder device; Fig. 9 a plan of Fig. 8,

and Fig. 10 is a side view showing the part K and connections.

The frame A is of suitable construction to support the operating parts of the machine, including bearings for the main shaft B, sup ply-spindles O, and series of hollow driving shafts or sleeves D, upon each of which turns freely a belt-pulley 2, recessed at one end to constitute one member of a clutch, the other member, 3, of which slides on but turns with the shaft 1). As shown, the shafts of the two series are oppositely arranged, two shafts axially in line across the frame, and a continuous belt E passes over the pulley 2 of one shaft, down and beneath two pulleys 4 5 on the main shaft B, and up and over the pulley Q of the opposite shaft,

The pulleyet is fixed and the pulley 5 loose, and the belt E is thus driven to drive each of the oppositely-arranged shafts. the pulley 5 being an idler. Each shaft D is hollow and carries a drum or roll F, and above cach roll is an inclined spindle 6, supporting a cop-tube holder 7 and turning in a support shown as a box 8, from one side of which extends a trunnion 113, that turns in a socket of an arm 9, pivoted at 10 to a lug 12 on the frame. Ooilars 10() on the spindle, Fig. 1, hold it in place. The holder, on which a conical cop-tube is applied, ean thus be rotated by contact with the roll, rise as the cop is wound, and will always maintain one side of the cop in contact with the roll.

As the holder is secured to the spindle and the latter turns in the box, the lubricant is applied to the part in the box, so that the liability of oil being deposited on the cop, which is incurred when the holder turns on the spindle, is avoided.

The tension device G may be of any suitable construction. As shown it is supported by a hanger 18, recessed to receive and support a cross-bar l5, from which extend two rods 16 16 and through which passes loosely a rod 14. On the .rod 14: and on two rods `16 16, extending from the bar 15, are supported two bars 17 18, the former immovable and the latter capable of sliding on the rods and pressed outward by a spring 1) against a nut Q3 on the threaded end of the rod 1&1, by turning which nut the bar 18 is shifted. A jam nut serves to hold the nut Q3 after adjustment. The bars 17 18 carry alternately-arranged L-shaped fingers 2O E21, the short sections extending at right angles to the inner faces of the bars 17 18 and the long sections extending outward and bent alternately in opposite directions at the ends, and by pressing inward the bar 18 the lingers 21 connected therewith are carried inward away from the stationary fingers 20, and the yarn may be passed vertically between the two series of fingers, after which, on releasing the bar 18, it is carried outward by the spring', carrying' its lingers between the fixed fingers and bending the yarn in a tortuous course, that secures a tension thereon, increased in proportion as one series of lingers is carried beyond the other, determined by the position of the nut 23. It will be evident, however, that the bar 18 can move inward against the stress of the spring in case of any excessive draft on the yarn. Each tension device isarranged above one of the supply-spindles, and a curved g'uide-plate 24 directs the yarn from the tension device toward the reciprocating notched guide H.

The guide H slides in a longitudinal slot in a bracket 32 on the bed of the machine, and the yarn passes to the notch constituting the eye of the guide, over a curved plate 31, which is hung between ears of the bracket 32, so that by swinging the plate upward the yarn may be lifted from the eye, permitting the guide to play without aecting the yarn. An arm 52 on one of the pivots of the plate 31 tends to keep it in the position shown in Fig. 2. The g'eneral movements of the machine may thus be continued after any or all of the driving-rolls are stopped, as hereinafter described, this stopping being' effected by disengaging' the clutch-sections. It will be seen that by thus lifting' the yarn out of the guide the breakage of' the yarn is prevented when the winding' is stopped, while the guide continues to reciprocate. In its passage over the guideplate 24 the yarn crosses a slot 33, through which extends a drop-wire 34, the bent end of which, Fig'. 1, beai's on and is supported by the yai'n so long as the .latter is taut or unbroken. On the slacking' or breaking of the yarn, however, the bent end of the wire will swing' downward through the slot and the upper end will shift its position and operate the stop devices.

rIhe stop devices operate to detach the yarn from the guide to shift the clutch to ai'rest the rotation of the single driving-drum by which the slack or broken yai'n is being wound and also to actuate a detent which supports the cone-holder while loose ends are being pieced and to open the tension and to force the drop-wire back to normal position. fhile capable of being' differently constructed, the stop devices consist of a rod 35, 1 and 4, sliding in the hollow sleeve D and projecting outward with an outer rounded knob or end 36 and connected, by a pin 121 extending through a slot in the sleeve D, with the member 3 of the clutch, which when the winding-roll is to be rotated engages the other member, 2, under the action of a spring 37. (See Fig. 1.)

The rod 35 is pressed and held inward by the contact of its knob 36 with a knob 38 on an arm 39, swinging' across the end of said ,lugs 43, and a lever 44, Fig. 4, pivoted to the frame, has pivoted to its upper end a dog 45, having' a lug 46, and said dog extends over the upper end of the drop-wii'e 34, and when the lower end of the latter drops cn breaking or slacking' of the yarn, the upper end lifts the dog and the lug 46 is engaged by .one of the lug's 43 and the dog and upper end of the lever 44 are carried inward and the lower end of the lever 44 moves outwai'd in the direction of its arrow, Fig'. 4, to operate a suitable detent. Thus it carries a tooth 47 on the lever 44 away from a tooth 48 on a disk V49 on the rod 40. As the teeth 47 48 are disengaged the spring' 41 rocks the rod 40 and the arm 39 is carried with its knob 38 opposite to the end of the rod 35, pressing the latter back and carrying the member 3 of the clutch away from the member 2 and stopping the rotation of the drum F. As the drum is arrested the plate 31 is automatically lifted to remove .the yarn from the notch in the thread-guide by the vibration of an arm 50, Fig'. 3, at the inner end of the rod 40, which is connected by a slotted link 51 to an arm 52 on one of the pivots of the g'uide-plate 31. The link 51 is slotted, as it has a greater motion than is required to be impai'ted to the plate 31. Vhen the drum stops, the conehlder may be lifted to enable the operator to get the loose end and piece the yarn. To hold it in its upward position, I provide the detent K, Fig'. 3 and Fig'. 10, which, as shown, is an eccentric provided with an arm connected by a link 56 to allow a little lost motion with the upper end of the arm 50 to swing with the latter and eng'age a rod 57, connected to the arm 9, supporting the cone-holder. rlhe link 56 is slotted, as it has a greater motion than is required to be impai'ted to the detent K. Said rod bears on a roller-stud 6() and is clamped between the latter and the eccentricdetent when the cone-holder is lifted and holds the latter in elevated position; but when the shaft 40 isturned to carry the arm 39 away from the end of the rod 35 the eccentric is also turned and the rod 57 is released, allowing the cone to drop onto the drum. It will be evident that while the detent when bearing on the rod 57 prevents downward motion the rod can be raised freely.

A rod 72, passing through a hole 102 (dotted lines, Fig. 4) in the frame, is pivoted to the inner face of the wheel 49 and has a hooked end extending over the dog 45, so as to draw down the latter to normal position when the shaft 40 rocks to effect the disengag'ing of the IOO IlO

'reaeoi clutches. The lever 44 is thrown inward at the lower end by the action of gravity, which may be supplemented, if required, by a spring, so that the lever naturally tends to occupy a Vertical position.

It will be seen that as soon as arm 39 swings to the left, Fig. 4, the dog 45 will be forced downward by the action of the rod 72, attached to the disk 49 and hooked over the dogI 45, and by Contact with the drop-wire will restore the latter to-position.

The swinging of the lever 39 away from the rod 35 is effected by hand when the machine is to be started. As soon as the plate 31 drops the yarn is carried b v the operator to a position to be engaged by the upper rounded end of the thread-guide, and the yarn then passes over said end and into the guide-slot.

The rod 14 of the tension device is threaded at the inner end, and a circular nut 62 turns thereon and bears against a collar .w between the nut and the bracket 13.

The stopping' mechanism will open the tension device to allow the yarn to be drawn freely to piece it. This is effected by connecting the nut 62 by a link 171 with an arm 17() on the shaft 40, so as to turn the nut and permit the rod 14 to move longitudinally and open the tension. A cam will effect the same purpose as the nut.

There are material objections incident to the sudden reversing action of a cam for operating' the reciprocating thread-guide, which reversal if quick enough to secure the requisite sharp bends at the ends of the helices in the cone results in extreme vibration, pounding, and wear, to avoid which the speed and consequent production must be reduced. To secure the requisite quick reversal of the lay of yarn in the cop without the objections incident to the use of a cam, l make use of a revolving' crank-pin connected with the reciprocating guide and so operated as to accelerate the speed of rotation of the pin as the guide approaches the ends of the cop, and I have found that this enables me to increase the speed of the machine over that which would be possible with a cam.

As shown, the crank-pin is carried upon a support 80, which is a disk and which serves also as a fly-wheel, having a sleeve 100 rotating in a hollow hub 101 and driven by gears 85 86 from the main shaft B, and the crankpin 7 O is connected by a connecting-rod 74 to a pin 99 at the end of an arm 75 on a rockshaft 76, an arm 77 carried with which is connected by a link 7 8 to the carrier of the thread-guide. The arms 7 5 77 are approximately in line and nearly horizontal when the crank-pin 70 is in its upper position. These parts, as shown, are so arranged that the guide will be at the limits of its movements when the arm 7 5 is nearly horizontal or nearly vertical and the pin 70 is either at the top or bottom position. If the pin 7 O were secured fixedly to the support 80, the carrier would approach each limit of its movement with a gradually-retarded speed and the yarn instead of being reversed abruptly would be laid with a wide sweep or curve and result in impairing the form of the cop and in a loose package at the ends. l therefore combine with the pin means for causing' it to travel round the axis of the support with a changing radius and increasing its speed of movement at different parts of its path. Thus the pin is secured to a lever 81, slotted at its end to receive the eccentrically-mounted pin 83 and pivoted tothe support 80 by a pin 82 and suitably vibrated on its pin 82, as by means of an eccentrically-mounted pin 83 on the end of a shaft J, extending through the sleeve 100, which shaft turns in a direction the reverse of that of the support 80, but at the same speed. This reverse movement of the shaft J is effected from the shaft B by gears 71 172 73, Figs. 1 and 2. The parts are so arranged that as the pin 7 0 approaches either upper or lower position the eccentric-pin 83 will vibrate the lever 81 in a manner to impart a more rapid movement to the pin 70 in the direction of its travel and secure a quick reversal of movement of the thread-guide. The pin 7() as a resultant of the two different motions described is thus at different points of its revolution round the axis of the shaft J moved iirst with an increased speed over that of the support and then with a decreasingspeed. and, further, the pin during these movements is carried about the center of the shaft .l and also in a curve having the pin 8211s a center, whereby the pin 70 moves approximately ina circle, but deflected at intervals radially to and from the axis of the shaft J. This action results in an abrupt reversal of the motion of the guide at each end, but without jars or shocks.

To secure a quick .bend in the lay of the yarn, I pivot the arm 77 to an arm 90 on the rock-shaft 76, securing a spring 92 to the inner end of the arm 77 in such manner as to re- 'sist any movement of the arm on its pivot and arranging adjustable stops 94 95 on a stationary bracket 96 in such position that as the tail of the arm 77 is carried to either side it will strike one of the stops, insuring a quick extended movement in the same direction to the outer end of the arm with which the threadguide is connected.

The pin 7() may be shifted as described in different ways, and the movements set forth in connection with other parts of the apparatus may be effected to secure the same results by different means.

In machines as ordinarilyconstructed when a conical cop is being wound with a drum wind the spindle is not parallel to the driveroll, but slants downward with relation thereto. At the start the contact-line between the ICO cop and the drive-roll is along a line in the plane of their axes. As the .thread mass grows and the cop swings upward the line of contact is gradually thrown out of the plane including the axis of the cop and the axis of the d rive-roll. As the apex end of the spindle rises more slowly than the base end, the cop and roll will assume the position of skewgears as the yarn mass grows and the spindle and its support swing upward. This results in reducing the contact between the roll and cop from a line the length of the cop to substantially a single point and tends to crowd the yarn on the surface and toward the large end of the cop and the stretch ing of the yarn causes loops, uneven winding, and uneven pressure and prevents a close and fine adjustment of the thread-guide in relation to said cop, which causes an irregular laying of the helices and also causes unevenness of pressure on the apex end of the package. To remedy this, I make use of the construction shown in Figs. 8 and 9, where the swinging arm 9 and box 8 have each a swivel connection, the box swinging in one direction on the trunnion 113, turning in the socket in the pivoted arm9 to permit the proper.

slant of the cop-spindle above mentioned, and in the other direction on a pivot 101 as the winding progresses. A pivot 114-. at the rear end of the box 8 secures one end of a connecting-rod 111, the other end of which swings on astationary stud 116, eccentric to the pivot 10 of the arm 9. The result is that as the yarn mass increases in diameter and swings upward one end of the part 8 swings about the center of the pin 10 on a curve 133, while the other end of the box or bearing 8 is thrown outward and will follow a path shown by the line 123. In other words, the two extremes of the package will swing in eccentric curves, and the line of Contact of the cop and roll will always be in the plane including the axis of the cop and the axis of the drivingroll. It will be seen that by changing' the position of the stud 116 any desired variation can be obtained and that by employment of an extensible connecting-rod 111, as shown, the conical cop can be adjusted' to a tine degree on the surface of the drivingroll.

1t will be seen that by a simple adjustment of the connecting-point of the rod 78 with the lever 77 the throw of the guide may be varied.

1t will be evident that where the acceleration of the ends of the traverse is not required a regular cani may be substituted for the peculiar wrist-pin-operating means specified in connection with the other features of the structure.
